• Manufacturer Part Number: SM5306A
• Description: Low Voltage, 3-channel Video Buffer
• Manufacturer: NPC [Nippon Precision Circuits Inc]

TYPICAL APPLICATION CIRCUIT
Application Circuit 1 (standard connection)
Application Circuit 2 (capacitively-coupled display module connection)

Capacitor connections to the SM5306A output pins are not required.
Short circuit OUT × pins to OFB × pins. In this mode, the sag compensation circuit does not function.
A gain of 0dB is suitable, since matching resistors are not required. In this case, it is recommended that a
1k Ω resistor be connected to ground.
